What
WebFetch, the tool Claude uses to read web pages, now keeps track of each address it fetches and short fingerprints of the requests made with it, up to 32 per address. It reports this as usage data (tengu_web_fetch_dedup_shadow), including:
whether the page was already cached
whether it was a repeat fetch, and how long since the previous one
whether the request and the agent asking were the same
how the result was produced: agent_raw, raw_markdown or secondary_model
Why
This is measurement only. Fetch results are the same as before.
